CAGE-LOCK.

Specification of Letters Patent.

Application filed. July 15, 1903.

Patented March 23, 1909.

Serial No. 43,64.8.

To all whom it may concern:

Be it known that I, Josue. W. UNGER, a citizen of the United States,residing at Christopher, in the county of Franklin and State ofIllinois, have invented a new and useful Improvement in Cage-Locks, ofwhich the following isa specification.

My invention is an improvement in cage locks and consists in certainnovel constructions and combinations of parts hereinafter described andclaimed.

Referring to the drawings forming a part hereof Figure 1 is a side viewof the improvement. Fig. 2 is an end View. Fig. 3 is a bottom plan view.Fig. 4 is a detail pers ective view of the releasing mechanism and ig. 5is a plan view of the locking device.

ihe present embodiment of the invention comprises a cage, composed ofparallel beams 1, connected by cross beams 2, suspended from a liftingbar 3, by means of hangers 4,,and the ends of the lifting bar arerecessed to receive the guides 5 of the shaft, in the usual manner. Theparallel beams 1 are also provided with guide brackets 6 cmbracingtheguides. ihe cage is provided with bearings 7 at each side, and at oneside of the transverse center, in which are journaled trunnions 8connected with a tilting frame to be presently described, for supportingthe car.

The tilting frame comprises a )latform or floor 9, supported onsubstantial y V-shaped brackets 10, one leg of the V being shorter thanthe other, as shown in Fig. 1, to bring the platform or floor intoregister with the On the longer legs of the \lshaped bracket are securedstirrups 11, in any suitable manner, and the stirrups are adapted torest on a cross bar 12, when the tilting frame is in normal position,that is with the floor 9 horizontal. The stirrups are arranged for enagement by sliding dogs or bolts 13, movab e in uide brackets 14 securedto the cross bar anc are normally retained in engagement with thestirrups by means of springs 15 contacting at one end with the guidebrackets and at the other with a loop 16 on the cross bar.

Levers 16 are ivoted to the cross bar as at 17, the upper en s of thelevers being pivoted to the inner ends of the dogs, and the outer endsare adapted to be engaged by a cam 18, secured to a shaft 19, journaledin a bearing 20 on the cross bar, and the lever is provided with anintegral cross arm 21, having at one end a weight 22, and at the other atreadle 23, which is engaged by a trip 26 when the cage is in dumpingposition. The tilting frame is provided with a transverse rod 24projecting at each side beyond the frame for grasping to move the frame,and the lifting bar 8 is connected with the usual hoisting rope or cable25.

In operation, the car is run onto the platform 9, which may be providedwith tracks for this purpose, and hoisted to the top of the shaft. W henin position for dumping, the treadle is engaged and depressed by thetrip 26 to withdraw the dogs or bolts, and the handles 24 are grasped totilt the frame. After the car is dumped the frame returns to its normalposition by gravity.

It will be observed that the treadle is pivoted to the cross arm as at27, so that should it meet an obstruction on the down trip, it may swingupward without moving the shaft. Should the treadle meet with anobstruction on its upward movement and the frame be unlocked, it wouldimmediately be reloeked automatically when the obstruction were passed.

It will be evident from the description that the device is automatic,both in locking and unlocking, and that it is both simple and efficientand not liable to easily get out of order.

I claim 1. The combination with the cage provided at each side withbearings eccentric to the transverse center, of a tilting frame havingtrunnions journaled in the bearings, said frame comprising a floor andsubstantially V-shaped brackets, the trunnions being at the apex of thebrackets, stirrups on the frame at the edge remote from the bearings, across bar on the cage on which the stirrups normally r st, springactuated bolts slidable on the cross bar and engaging the stirrups,levers pivoted to the cross bar each having one end connected with abelt, a shaft journaled on the frame and provided with a cam forengaging the free ends of the levers to withdraw the bolts when theshaft is oscillated, a cross arm on the shaft provided at its inner endwith a counter-balance, atreadle pivoted to the outer end, and a tripfor engagement by the treadle when the cage is in dumping position, saidtreadle being mounte ed to swing freely upward direction.

2.
